Pure CSS Animated Background
Creating a pure CSS animated background is a fun way to enhance the visual appeal of your website or web application. You can achieve this by using keyframes animations, gradients, and transitions. Here’s a simple example of how to create a CSS animated background.
In this example, we create an animated background using keyframes and linear gradients. The @keyframes rule defines a set of gradient backgrounds that transition smoothly from one color to another. The animation property applies these keyframes to the .animated-background element, creating a continuous animation.
You can customize the colors, animation duration, and angles to create the background effect you desire. This is just a basic example, and you can get creative with your designs by adding more complex animations and effects.
